Housing design

The EL3020 Gas Analyzer is designed in a 19-inch housing with 3 height units and IP20 protection.

Description of Analyzer Performance Characteristics

The performance characteristics of the analyzers are defined according to the international standard IEC 1207-1:1994 “Performance statements for gas analyzers”.

They are based on N2 as a companion gas. When measuring other gas mixtures, compliance with these characteristics can only be ensured if their composition is known.

Measurement principle

Non-dispersive infrared absorption photometers in the λ = 2.5-8 µm wavelength range can measure up to 4 compositions using 1 or 2 beam paths and 1 or 2 receivers per beam path in one gas path or two independent gas paths.

Measure up to 4 components in one gas path or two independent gas paths with 1 or 2 receivers per beam path.

Impact Effects

Flow rate effects

Flow rates in the range of 20-100 liters/hour: within the detection range

Correlated gas effects/cross sensitivity

Analyzer configuration must be aware of sample gas composition.

Selective measures to reduce associated gas effects (optional): Installation of interference filters or filter units, internal electronic cross-sensitivity correction of one sample component by other sample components measured by the gas analyzer.
